Abstract: Based on Landsat images from three phases in 2000,2008 and 2016,the linear spectral mixture model(LSMM) was used to extract the vegetation coverage of the Qinghai Lake Basin in the three phases. The results showed that there was a slight increase in vegetation coverage between 2000 and 2008,while the vegetation coverage indicated a very significant increase during 2008 to 2016,and the increase between 2008 and 2016 was closely related to the Qinghai Lake Basin Comprehensive Restoration Project initiated in 2008.

Key words: Qinghai Lake Basin, linear spectral mixture model, vegetation coverage change
